DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below.

FIG. 1 (a) is a front view showing the structure of a single sheet material removing apparatus according to the present invention, FIG. 1 (b) is a side view showing the structure of the single sheet material removing apparatus according to the present invention, FIG.
FIG. 2 is an enlarged schematic side view showing a configuration of a main part of a single sheet removing device according to the present invention.

Referring to the drawings, reference numeral 1 denotes a pallet;
2 is a pipe roller, 2a is a sprocket, 2b is a chain, L is a hydraulic lifter, and has a hydraulic lifter L on which a pallet 1 in which plate materials W are accumulated and stored can be placed on a lower frame FL, and covers the hydraulic lifter L. As shown in FIGS. 1 (a) and 1 (b), a plurality of sprockets 2a are disposed at symmetric positions on both sides of the hydraulic lifter L, and a chain 2b is mounted on the sprocket 2a.
Can be circulated by the rotation of the chain, and the chain 2
b, the pipe roller 2 is wrapped around the opposed annular chains by a length corresponding to the length of the work W, and the length of the virtual plane formed of a desired number and on which the plate material W can be placed is at least adjacent. The pipe 8 is provided so as to have the same length as the table 8 of the plate material processing machine P, and the pipe can be moved up and down on the head of the plate material W accumulated and stored on the hydraulic lifter L by the forward / reverse rotation of the sprocket 2a. A piston rod tip 3a of an upper and lower cylinder 3 that constitutes a roller conveyor CP and is fixed downward to the upper frame FU.
A magnet-equipped belt conveyor CB is provided in combination with the gripping device H, which is formed by suspending the suction device 5 via a stretch 4. This belt conveyor CB
Is provided with a horizontal arm Fh extending back and forth over an intermediate height position of the upper frame FU, and this horizontal arm Fh
The pulley 6a is pivotally supported on the front and rear end portions and on an extension of the intermediate height position of the upper frame FU.
A belt 6 is stretched over the lower belt, and the belt 6 is provided so as to be capable of horizontal circulation traveling by a drive motor M.
That is, the electromagnet 7 attached to and held by the horizontal arm Fh is provided close to the inside of the belt so that the side in contact with the plate material W is within the magnetic field range, and the plate material accumulated and stored via the pallet 1 on the hydraulic lifter. It is configured such that W can be conveyed while being suction-held.

Further, as shown in FIGS. 1B and 2, a space formed by a plurality of belt conveyors with magnets CB arranged in at least two rows and a plurality of rows at predetermined intervals can be raised and lowered freely. An adsorber 5 suspended via a stretch 4 provided at the end 3a of the piston rod of the upper and lower cylinders 3, a gripping device H having the adsorber 5 and a belt conveyor CB with magnets having electromagnets.
Are configured to cooperate with each other to minimize the tact time of a series of operations.

The operation will be described based on the above configuration.

By rotating the sprocket 2a, the chain 2
b, the pipe roller 2 is retracted so as to sink from the overhead of the plate material W accumulated and stored on the pallet 1 on the hydraulic lifter L, and the piston rod of the upper and lower cylinder 3 is moved while the overhead of the plate material W is empty. By the lowering operation of the tip 3a, the suction device 5 such as a vacuum pad is lowered via the stretch 4, the uppermost plate material W accumulated and stored on the pallet 1 is suctioned, and then the suction device 5 is raised to run the chain. Raise it even higher than the top of the road.

Then, the sprocket 2a is rotated in the reverse direction to rotate the chain 2b back to the original position, so that the pipe roller 2 can return to the uppermost surface of the chain running path so that the plate W can be placed thereon. In the case of a non-magnetic material such as stainless steel or aluminum, the adsorber 5 is released and the plate material W is transferred to the pipe roller 2 of the pipe roller conveyor CP.
The plate material W placed on the pipe roller 2 is carried and loaded on the work table 8 of the plate material processing machine P by rotating the sprocket 2a and circulating the chain 2b in the forward direction.

When the material of the plate is a magnetic material such as iron,
When the suction device 5 such as a vacuum pad is further raised, the plate material W abuts on the lower surface of the belt 6 of the belt conveyor CB with magnets and is sucked. At this time, the suction device 5 is released and retracted above the position of the belt conveyor CB. Then, the suction device 5 is peeled off from the upper surface of the plate material W, and the plate material W adsorbed on the lower surface of the flat belt 6 of the belt conveyor with magnet CB is moved by the belt conveyor CB. The work table 8 is carried onto the work table 8 of the processing machine P, and is securely moved to the rear end of the plate material W.
After the state of being placed on the upper side is confirmed, the electromagnets of the belt conveyor with magnet CB are demagnetized, and the operation of loading the plate material W into the plate material processing machine P is completed.

Further, instead of adding a slat conveyor or a pipe roller conveyor CP, a traveling device may be provided in the gripping device H and the plate material W may be traversed to the next station in a state where the plate material W is sucked. It is considered disadvantageous in tact time.

[0019]

According to the present invention, the magnet conveyor is combined with the holding device, and the pipe roller conveyor is provided so as to be able to come and go above and below the plate material stored and stored, so that it can be used irrespective of the material of the plate material. In particular, when handling a magnetic material such as iron, the tact time of a series of operations can be minimized, and the effect of shortening the time for loading the plate material can be exhibited.
